Boom 2
Loud, bassy beast; needs EQ, no aux.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Middleton 2 would be my pick as its soundstage is wider and 30 hours of battery is great. Bose sound link plus is the most portable of the three and has great sound as well. Both are good choices, I personally give the edge to Middleton 2.
The Bose SL Plus will likely be a solid fit for you as Bose has a pretty balanced sound, out of the box. Not sure if you’re looking for indoor v outdoor but you might look into getting two SL Flex and setting them up in stereo mode. They sound incredible.
I have 3, and each has its own use case. Bose Sound Link Plus: loud uni-directional loud speaker. Good sound, very loud in one direction, fairly durable, good battery. I slapped a bunch of stickers on it and take it to protests and such. Its heavy but easy to carry around with the rope handle. It's got some scratches from being dropped, but holds up pretty well. Marshel Middleton 2: great sounding multi-directional speaker. Great warm sound, decent battery. I use it for picnics and such. Not the most robust. Also looks cool as he'll. JBL Charge 6. Tough as nails, good sound, meh batteries. I get drunk and I drop things, and thing is a survivor. Multiple drops on to concrete and you can't even see any damage. Great for the beach.
Speaking of flaws, my Soundlink Plus will not connect to the Bose app, I'm desperate to reduce the bass on the equalizer. No problem with the flex just the plus? The app doesnt even feature the Plus? Confused?
People love the charge 6 the most from this lineup - its damn loud for the size. Personally im swapping mine for a bose soundlink plus but thats a lil more expensive. The soundlink flex 2 is a good option for you too though
Check out the Bose Soundlink Plus, Amazon has them on sale for $199 right now. I've had mine for a few months now and love it, its a little heavy but the sound quality and battery like make up for it
Tied between the Bose Sounlink Plus and Brane X. The Brane just has some incredible power but the Bose sounds great and has been awesome to take out to games
The Bose for sure! I have the sound link plus and it's been awesome, it's a little bulky but about the same as the other two. Battery lasts forever and the sound quality is awesome! I'd avoid the Marshall, I gave up on them after I went through 4 Stockwell's all with charging/battery issues.
